Digital device having a reset pad circuit that may be subject to hacker attack

A digital device, comprising:

• a reset pad circuit having a first input coupled to a first reset access port and configured to receive an external reset request, a second input coupled to a second reset access port and configured to receive an internal reset request, and an output, wherein the reset pad circuit is configured to generate a first reset state signal and includes a reset request propagating portion coupling the first and second inputs to the output of the reset pad circuit;
• an internal reset activation gate having at least one input coupled to an internal resource and an output coupled to the second reset access port of reset pad circuit, wherein the internal reset activation gate is configured to generate the internal reset request;
• a memory element having a first input coupled to the output of the internal reset activation gate, a second input coupled to the output of the reset pad circuit, and an output, wherein the memory element is configured to generate a second reset state signal when receiving the internal reset request until receiving the first reset state signal;
• and
• a reset forwarding gate coupled to the output of the reset pad circuit and the output of the memory element and configured to generate a system reset request in response to one or more of the first reset state signal and the second reset state signal.
